Driving unit for analog meter

Abstract

The present invention provides a driving unit for an analog meter. The size of the driving unit is modified into a column shape, so that the first tape and second tape of the stator unit can be placed in double layers, guiding more pins of the input terminal from the same side. The driving unit can simplify the manufacturing process, and the size of the components of the driving unit are greatly reduced, making assembly more flexible or emptying more space for other components. The more concentrated pin can be connected easily or can be provided with more options for connection.

1. A driving unit for analog meter, wherein the driving unit is placed on the predetermined location inside the housing of the analog meter to drive a deceleration unit, and the driving unit comprising:
 a stator unit, which is longitudinal hollow column shaped, including a longitudinal hollow column, a claw, a coil set and an input terminal; and 
 a rotor unit, which is placed inside the column of the stator unit, including a mandrel and magnetic rim; 
 wherein the deceleration unit comprises a first small gear wheel placed on the mandrel of the rotor unit, a first big gear wheel moving with the first small gear wheel, a second small gear wheel at the bottom of the first big gear wheel, and a second big gear wheel connected to the second small gear wheel, a decelerated force coming from a mandrel connected to the center of the second big gear wheel. 
 
   
   
     2. The driving unit defined in  claim 1 , wherein the input terminal of the stator unit is connected by pins. 
   
   
     3. The driving unit defined in  claim 1 , wherein the coil set of the stator unit includes a tape A for coil set and tape B for coil set, so that the input terminal is placed between the tape A for the coil set and tape B for the coil set. 
   
   
     4. The driving unit defined in  claim 1 , wherein the input terminal extends out through a lateral through hole of the housing. 
   
   
     5. The driving unit defined in  claim 1 , wherein the external part of the stator unit and rotor unit is assembled into one piece by a casing. 
   
   
     6. The driving unit defined in  claim 5 , wherein the connecting positioning part is placed on the predetermined part of the casing.
